out of the two, i'd say flowtech because its not a knockoff and its a one piece. but if i were in your situation i would go with the mac. i have that and absolutly love it

 

lol, I was just trying to be the bad guy and choose something not listed, lol. Damn I didn't think anyone would go along, of course that's what I have is the mac or xpipe. The 2 piece didn't bother me. At first though I looked at it for hours trying to figure out what the hell I just got, lol.

 

yeah i got the flowtech at first but it looks nothing like the pic. it was not 1 piece, so i sent it back and got a mac o/r h pipe and i love it. spend the extra money and get a mac

 

Get teh MAC. I got mine for 135 shipped off ebay. NEW
